Wondering how to build an app? There are a number of different approaches that are now open to you. Tools such as React Native and Flutter (Google's recent addition to the party) are opening up new possibilities when it comes to mobile app development. Read on for our rundown of five different ways to build an app, to help to decide which one is right for you.
01. Native
The default way of developing on mobile is to write native code for each device – usually Java for Android and Swift for iOS. This can give you the best result, but the problem is that you then have two codebases to maintain.
02. WebViews
The earliest way to get around this was to build 'hybrid' apps that were essentially web pages rendered within an app container (referred to as WebViews). The Ionic framework is an example of this approach. This has limitations in user experience and relies on a JavaScript 'bridge' to interact with native services, which can impact performance.
03. React Native
The release of React Native gave us the ability to write JavaScript code (with React syntax) that used entirely native widgets. It still uses a JavaScript runtime but the presentation is not HTML and it doesn't use a WebView. This takes away a major limitation of older hybrid apps but can still suffer performance issues due to reliance on the JavaScript 'bridge'.
04. Flutter
While they offer similar reactive development styles, the major difference between Flutter and React Native is that Flutter dispenses with runtime JavaScript completely and compiles native code for multiple platforms. This offers superior start-up times and app performance. For more on this framework, take a look at our guide to getting started with Flutter.
05. Progressive Web Apps
One possible future for mobile development moves away from the native environment completely. Web APIs now enable much more extensive interaction between web pages and devices than in the past and service workers mean pages can be cached and work offline. The technology isn't quite there yet but some people are betting that the future of mobile apps is actually web technology.
